Hey so, i don't know if you're aware (and again, i don't know if there's any correlation between), but i've read that the FF8 Remastered on Steam is broken right now due to a windows update, i guess of May 2020, and it haven't been fixed.
The "broken" thing is similar to what happend to me: game runs at something like 20FPS making it very bad to play.
I haven't tested it myself since i don't have the Remaster, but i read a lot of comments about this on the Steam reviews.
It's really a straight guess: if those problems are somehow correlated, maybe windows is to blame...
Thanks for the attention btw.
